It is 74.4 miles from Dwane and Patti's house to Martha's house. Patti leaves home at 10:00 and drives toward Martha's house. Dwane and Martha set off half an hour later from their own houses and drive toward the other's house. The average speed of the three friends is 54 mph and they all meet at 11:06. How fast does each drive?
Sorry for my error. Please see Steve's answer.
Thanks for your correction Steve. I assumed they traveled the same distance which was the flaw in my set up. Thanks again.
